Before you begin: Ensure you are in your normal driving position with your seat and steering wheel properly adjusted.
1. Inside Rearview Mirror
Action: Adjust the mirror to frame the entire rear window.
Result: You should see the highway directly behind you without moving your head.
2. Driver's Side Mirror (Left)
Action: Lean your head to the left until it almost touches the driver's side window. From this position, adjust the left mirror outward until you can just barely see a sliver of the rear-left corner of your car.
Result: As a vehicle leaves your rearview mirror, it should immediately appear in your left side mirror.
3. Passenger's Side Mirror (Right)
Action: Lean your head to the right until you are near the center console. From this position, adjust the right mirror outward until you can just barely see a sliver of the rear-right corner of your car.
Result: As a vehicle leaves your rearview mirror, it should immediately appear in your right side mirror.
